Abstract: Traditional pollution monitoring methods are mainly carried out by fixed base stations, but these are inflexibility and expensive, which are no longer sufficient to deal with the problems of growing pollution. A new data acquisition mode—Mobile Crowdsensing—provides a new idea for large-scale data perception. In order to grasp the research status of pollution data collection of Mobile Crowdsensing in time, the existing researches at home and abroad are systematically and comprehensively reviewed, and feasible schemes are provided for the application of crowdsensing in smart phones based on the existing research. Firstly, the development stages of pollution collecting technology is elaborated. Then, the advantages and disadvantages of different crowd-sourced pollution collection systems are compared and analyzed, and the advantages and disadvantages of the key technologies used and the applicable scenarios are explained. Finally, the problems existing in the collection of pollution data under crowdsensing are summarized, and the future research focus is prospected.
